Thanks for the trace. I think that we've finally caught something.
>From the grub-pc.log:
rmdir: failed to remove `/var/lib/os-prober/mount': Device or resource busy
There is also this trace in dmesg at the same time:
[217080.308127] INFO: task grub-setup:21796 blocked for more than 120 seconds.
[217080.308136] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables
this message.

Which would suggest that the sync call in grub-setup didn't return and
matches the 1rst ps output.
BTW I noticed that there are I/O errors on sdb

but that shouldn't be related to the grub-pc upgrade since it was not
mounted at the time of the failure.
Just to confirm your setup. This is a dual boot system with windows on sda1,
linux on sda3, a data disk (which filesystem) on sdc, another unused drive on
sdb, and an external drive on sd. grub2 is installed on MBR of sda and it's not
a virtual machine ?
Is there anything else specific to your setup ?
Do you have some "boot sector virus protection" enabled in your bios ?
